A road block closes access to Bastendorf Beach outside Coos Bay, Ore., on Tuesday, Aug. 19, 2014, where authorities say a drive-by gunman shot five vehicles, killing a Michigan man as he slept, then shot and killed himself. Authorities say they have reason to believe the gunman, Zachary Levi Brimhall, 34, of Dillard, Ore., may also have "done harm" to his father, whose vehicle was found in another rural area of Coos County. The investigation was slowed by the discovery of explosives in Brimhall's vehicle. (AP Photo/Angelica Carrillo/KCBY)

Zachary Levi Brimhall had picnicked with his parents at a remote spot in Oregon's Coast Range last weekend then stayed to camp.

But on Monday, authorities say Brimhall called his father to say his car was stuck. When Ray Brimhall arrived, his son shot him five to 10 times, then drove 50 miles to Bastendorff Beach outside Coos Bay and shot up five parked cars in the dark.

Coos County District Attorney Paul Frasier says one man was fatally shot as he slept in his parked vehicle.

David Jesse Hortman of Michigan had told a co-worker at a recreation vehicle show he was taking a week off to drive the Oregon Coast, looking at the ocean and sleeping in his car.
